[PATCH 1/3] bitbake: fetch2/repo: add support for projects to be fetched simultaneously

["Sourabh Banerjee" <sbanerje@codeaurora.org>]

repo tool can fetch projects simultaneously.
As per repo sync documentation:
  Usage: repo sync [<project>...]
  Options:
    -j JOBS, --jobs=JOBS  projects to fetch simultaneously (default 1)

By supplying jobs=<some_number> recipe can choose to use the
simultaneous fetch feature of repo tool.
Example:
  SRC_URI = "repo://REPOROOT;protocol=git;branch=main;manifest=default.xml;jobs=8"
